Abstract
The present invention is generally directed to, in one embodiment, a composite electrospun nanofiber being formed of a nanofiber and a particle at least partially embedded within the nanofiber, the particle having a width that is greater than the diameter of the fiber so that at least a portion of the particle is not covered by the nanofiber.
Claims23
A composite electrospun nanofiber comprising:
- an electrospun nanofiber and a particle at least partially embedded within the electrospun nanofiber, the particle having a width that is greater than the diameter of the electrospun nanofiber.
A composite nanofiber comprising:
- a nanofiber having a diameter, a first end and a second end, and a particle having a width that is greater than the average diameter of the nanofiber, the particle interposed between and attached to the first and second ends of the nanofiber.
A method for forming a web comprising:
- providing a polymer solution;
- dispersing particles into the polymer solution;
- and
- electrospinning composite nanofibers onto a surface, wherein at least some of the particles are embedded into nanofibers.
